Protective measure
Skin contact: Remove contaminated clothing and rinse with plenty of running water.
Eye contact: Lift eyelids and rinse with running water or saline. Seek medical attention.
Inhalation: Quickly remove from the scene to fresh air. Keep your airway clear. Administer oxygen if breathing is difficult. If breathing stops, give artificial respiration immediately. Seek medical attention.
Ingestion: Drink enough warm water to induce vomiting. Seek medical attention.
Fire protection measures
Hazardous properties: inorganic oxidizer. Contact or mixing with organic matter, reducing agent, inflammable matter such as sulfur, phosphorus, etc., may cause the danger of combustion and explosion. Explosions can occur when heated sharply.
